CB Mould Services will feature two molding products: its SGD gas-venting valve and CA locking cylinder. Designed to help resolve common effects of poor cavity venting, the SGD valve allows gas to escape from a venting hole that automatically closes under the pressure of the plastic. It can be placed inside the cavity where the filling pattern produces gas traps to reduce the counter pressure of the air, improving the filling pattern.

The side-action CA locking cylinder is designed to withstand plastic injection force during the injection phase. Its compact design enables the whole part to be embedded into the cavity, reducing necessary mold dimensions and core length, and consequently reducing thermal expansion.
